UNITED STATES- PATENT OFFICE.

ROY BEARD, OF BOWLING GREEN, KENTUCKY.

DRILLING-MACHINE.

. T 0 all whom it concern:

Be it known that I, ROY BEARD, a citizen of the United States, residing at Bowling Green, in the county of Warren and State of Kentucky have invented a new and use- 111 Drilling-Machine, of which the following is a specification.

This invention has reference to drilling machines, and more particularly to the construction of the walking beam thereof, it being an object of the invention to provide a walkingibeam which may bemoved to a position remote from the path of travel of the tools, when the same are being removed A further object of the invention is the provision of means to relieve the beam of the machine of undue strain by distributing the strain throughout the several elements of the frame.

VViththe foregoing andother objects in view which Will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 illustrates a fra ental side elevation of a drilling machine showing the invention as applied.

Fig. 2 illustrates a sectional View taken on line 2- 2 of Fig. 1.

Referring to the drawing in detail, the reference character 5 designates the derrick legs, which are of the usual construction, the same being spaced apart, and held in such spaced relation by means of the crossbars 6. g V

The usual walking beam indicated by the reference character 7 is pivotally supported by the frame, and has the side bars thereof operating on opposite sides of the derrick legs, the same being operated by means of the power wheel 8 which is pivotally supported by the frame and is connected to the walking beam 7 as by means of the connecting arm 9, whereby pivotal movement is imparted to the walking beam 7.

The walking beam forming the important feature of the invention includes the auxiliary arm 10, which is pivotally supported by Patented Sept. 28, 1920.

Application filed July 3, 1920. Serial No. 393,915.

vided a head 12 formed on one end of the arm 10, which head contacts with the drill chain 12, which has one extremity thereof secured to the arm 10 as by means of the hook element 13 carried by the upper surface of the arm 10.

Carried by the upper surface of the arm 10 is adoearing plate 14, which provides a bearing surface for the roller 15 carried between the arms of the link 16 which has its lower ends secured to the beam 7 as at l7,the upper end thereof being secured to the brace arm 18, as at.19.

From the foregoing it is obvious that as the Walking beam 7 moves downwardly, pressure is brought to bear on one extremity of the arm 10 to cause the opposite end thereof to be elevated, thus raising the drill line and the drill carried thereby.

When it is desired to remove the tool from the well, the flexible member 20 is operated to move the outer end of the arm upwardly out of the ath of travel of the tool being removed, t ereby facilitating the removal of the tool.

It is believed that in view of the foregoing description, a further description as to the operation of the device is unnecessary.

Having thus described the invention, what is claimed as new is 1. In combination with the derrick legs and the main walking beam of a drilling machine, an auxiliary walking beam pivotally supported by the derrick legs, a link member carried by the main walking beam and embracing a portion of the auxiliary walking beam,'whereby movement of the walking beam causes a relative movement of the auxiliary walking beam,-and anti-friction means carried by the link member and operating on the auxiliary walking beam.

2. In combination with the derrick legs and the main walking beam of a drilling machine, a relatively short auxiliary walking beam pivotally supportedintermediate its ends, means carried by the main walking beam and operating over the-auxiliary walking beam, whereby movement of the main walking beam causes a relative movement of the auxiliary walking beam, and means for moving the auxiliary walking beam to a position at substantially'right angles to the main walking beam.

3. In combination with the derrick legs machine, an auxiliary walking beam pivotbeam, a roller carried by the link and contacted With the auxiliary walking beam,

, means for pivoting the main walking beam to cause a pivotal movement of the auxiliary walking beam, and means for securing the auxiliary walking beam in a position at substantially right angles to the main walking beam.

machine, an auxiliary walking beam pivot Y allv supported by the derrick legs, means carried by the main walking beam and contacting with the auxiliary walking beam, for moving the auxiliary walking beam, a head formed on one end of the auxiliary walking beam, a bearing plate supported on the upper surface of the auxiliary walking beam, and a roller associated with the main 4. In combination with the derrick legs/ walking beam and operating on the bearing and the main walking beam of a drilling machine, an auxiliary walking beam pivotally supported by the derrick legs, means for connecting the main walking beam and auxiliary walking beam, whereby movement of the main walking beam produces a relative movement of the auxiliary Walking beam, andv means for operating the main walking beam.
